*1 Power with which the driver can be used without
activating the built-in thermostat.
A built-in thermal fuse and a thermal protector are provided for safety.
The circuit should be so designed that the power supply will be turned off as the thermal protector operates.
The built-in thermal fuse blows depending on changes in heat dissipation condition, operating temperature limit, power
supply voltage or load.
Mount the regenerative resistor on a machine operating under aggressive regenerating condition (high power supply
voltage, large load inertia, shorter deceleration time, etc.) and make sure that the surface temperature will not exceed
100°C.
